These bottles are perfect for foaming soap. You can use any of the castile soaps we have at the refillery in this bottle. You only need 1/5th castile soap and rest water so it goes a long way.
These are plastic unfortunately as there are no glass ones currently on the market that we are aware of. So please make sure you keep reusing it at our refillery.
The bottles are a little expensive which is due to the special pump spray which you need to foam the product. It is completely different to a spray or pump trigger.
